Abstract
PANoptosis induces programmed cell death (PCD) through extensive crosstalk and is associated with development of cancer. However, the functional mechanisms, clinical significance, and potential applications of PANoptosis-related genes (PRGs) in colorectal cancer (CRC) have not been fully elucidated. Functional enrichment of key PRGs was analyzed based on databases, and relationships between key PRGs and the immune microenvironment, immune cell infiltration, chemotherapy drug sensitivity, tumor progression genes, single-cell cellular subgroups, signal transduction pathways, transcription factor regulation, and miRNA regulatory networks were systematically explored. This study identified 5 key PRGs associated with CRC: BCL10, CDKN2A, DAPK1, PYGM and TIMP1. Then, RT-PCR was used to verify expression of these genes in CRC cells and tissues. Clinical significance and prognostic value of key genes were further verified by multiple datasets. Analyses of the immune microenvironment, immune cell infiltration, chemotherapy drug sensitivity, tumor progression genes, single-cell cellular subgroups, and signal transduction pathways suggest a close relationship between these key genes and development of CRC. In addition, a novel prognostic nomogram model for CRC was successfully constructed by combining important clinical indicators and the key genes. In conclusion, our findings offer new insights for understanding the pathogenesis of CRC, predicting CRC prognosis, and identifying multiple therapeutic targets for future CRC therapy.

Contribution of Matrix Metalloproteinase-2 and Matrix Metalloproteinase-9 to Upper Tract Urothelial Cancer Risk in Taiwan. Life (Basel) 2024; 14:801. [PMID: 39063556 PMCID: PMC11277778 DOI: 10.3390/life14070801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Revised: 06/20/2024] [Accepted: 06/22/2024] [Indexed: 07/28/2024] Open
Abstract
Matrix metalloproteinase (MMP)-2 and -9, which degrade type IV collagen, are linked to cancer invasion and metastasis. Gene polymorphisms in MMP-2 and MMP-9 can influence their function, impacting cancer development and progression. This study analyzed the association between polymorphisms MMP-2 rs243865 (C-1306T), rs2285053 (C-735T), and MMP-9 rs3918242 (C-1562T) with serum concentrations of these enzymes in upper tract urothelial cancer (UTUC) patients. We conducted a case-control study with 218 UTUC patients and 580 healthy individuals in Taiwan. Genotyping was performed using PCR/RFLP on DNA from blood samples, and MMP-2 and MMP-9 serum levels and mRNA expressions in 30 UTUC patients were measured using ELISA and real-time PCR. Statistical analysis showed that MMP-2 rs2285053 and MMP-9 rs3918242 genotypes were differently distributed between UTUC patients and controls (p = 0.0199 and 0.0020). The MMP-2 rs2285053 TT genotype was associated with higher UTUC risk compared to the CC genotype (OR = 2.20, p = 0.0190). Similarly, MMP-9 rs3918242 CT and TT genotypes were linked to increased UTUC risk (OR = 1.51 and 2.92, p = 0.0272 and 0.0054). In UTUC patients, TT carriers of MMP-2 rs2285053 and MMP-9 rs3918242 showed higher mRNA and protein levels (p < 0.01). These findings suggest that MMP-2 rs2285053 and MMP-9 rs3918242 genotypes are significant markers for UTUC risk and metastasis in Taiwan.

Abstract
Aim: The matrix metalloproteinases (MMPs) inhibit tissue inhibitors of metalloproteinases (TIMPs), playing a notable role in various biological processes, and mutations in TIMP2 genes impact a variety of urinary cancers. In this study, we analyze and evaluate the potential involvement of the TIMP2 418 G/C and MMP gene polymorphism in the etiology of urinary cancer. Methodology: For suitable case-control studies, a literature search was undertaken from various database sources such as PubMed, EMBASE, and Google Scholar. Incorporated into the analysis were case-control or cohort studies that documented the correlation between TIMP2 418 G/C and urological cancers. MetaGenyo served as the tool for conducting the meta-analysis, employing a fixed-effects model. The collective odds ratios, along with their corresponding 95% confidence intervals, were calculated and presented to assess the robustness of the observed associations. Results: A total of seven studies involving controls and cases out of recorded 1265 controls and 1154 cases were analyzed to ascertain the significant association of the TIMP2 gene with urologic cancer. No statistically significant correlation was observed between allelic, recessive, dominant, and overdominant models for the genetic variant under investigation. A 95% confidence interval (CI) and odds ratio (OR) were computed for each model, considering p-values <0.05. The OR and 95% CI for the allelic model were 0.99 and 0.77-1.27, respectively, whereas the respective values were 1.00 and 0.76-1.32 for the recessive model. In the dominant contrast model, OR and 95% CI were 1.09 and 0.62-1.90, while the same were 0.93 and 0.77-1.12 for the overdominant model. A funnel plot was used to reanalyze and detect the results as statically satisfactory. Conclusions: As a result of the data obtained, the TIMP2 gene polymorphism does not correlate statistically with cancer risk. The significance of this finding can only be confirmed using a large population, extensive epidemiological research, a comprehensive survey, and a better understanding of the molecular pathways associated.

Abstract
Colorectal cancer (CRC) remains a major cause of morbidity and mortality. Therapeutic approaches for advanced CRC are limited and rarely provide long-term benefit. Enzymes comprising the 24-member matrix metalloproteinase (MMP) family of zinc- and calcium-dependent endopeptidases are key players in extracellular matrix degradation, a requirement for colon tumor expansion, invasion, and metastasis; hence, MMPs are an important research focus. Compared to sporadic CRC, less is known regarding the molecular mechanisms and the role of MMPs in the development and progression of colitis-associated cancer (CAC) - CRC on a background of chronic inflammatory bowel disease (IBD) - primarily ulcerative colitis and Crohn's disease. Hence, the potential of MMPs as biomarkers and therapeutic targets for CAC is uncertain. Our goal was to review data regarding the role of MMPs in the development and progression of CAC. We sought to identify promising prognostic and therapeutic opportunities and novel lines of investigation. A key observation is that since MMPs may be more active in early phases of CAC, using MMPs as biomarkers of advancing neoplasia and as potential therapeutic targets for adjuvant therapy in those with advanced stage primary CAC rather than overt metastases may yield more favorable outcomes.

Abstract
To provide a comprehensive account of the association of MMP-9 gene polymorphisms (rs3918242) with susceptibility to cancer. A literature search for eligible candidate gene studies published before May 27, 2022 was conducted in PubMed, Medline, Google Scholar and Web of Science. Potential sources of heterogeneity were sought out across subgroups and sensitivity analysis. Publication bias were also estimated. Overall, a total of 37 articles with 7616 cases and 8165 controls for rs3918242 gene polymorphisms were enrolled. Our meta-analysis suggests that MMP-9 rs3918242 might be associated with breast cancer and gastric cancer susceptibility, and perhaps reduce the risk of lung cancer.

Abstract
PURPOSE This study aims to evaluate the value of tissue inhibitors of MMPs-2 (TIMP-2) to indicate 5-Fluorouracil (5-Fu) resistance status in colorectal cancer. METHODS The 5-Fu resistance of colorectal cancer cell lines was detected using Cell-Counting Kit-8 (CCK-8) and calculated using IC50. Enzyme-linked immunosorbent assay (ELISA) and real time-quantitative polymerase chain reaction (RT-qPCR) were used to detect TIMP-2 expression level in the culture supernatant and serum. Twenty-two colorectal cancer patients' TIMP-2 levels and clinical characteristics were analyzed before and after chemotherapy. Additionally, the patient-derived xenograft (PDX) model of 5-Fu resistance was used to evaluate the feasibility of TIMP-2 as a predictive biomarker of 5-Fu resistance. RESULTS Our experimental results display that TIMP-2 expression is elevated in colorectal cancer drug-resistant cell lines, and its expression level is closely related to 5-Fu resistance. Moreover, TIMP-2 in colorectal cancer patient serum undergoing 5-Fu-based chemotherapy could indicate their drug resistance status, and its efficacy is higher than CEA and CA19-9. Finally, PDX model animal experiments reveal that TIMP-2 can detect 5-Fu resistance in colorectal cancer earlier than tumor volume. CONCLUSION TIMP-2 is a good indicator of 5-Fu resistance in colorectal cancer. Monitoring the serum TIMP-2 level can help the clinician identify 5-Fu resistance in colorectal cancer patients earlier during chemotherapy.

Abstract
Anaesthetics may modify colorectal cancer cell biology which potentially affects long-term survival. This study aims to compare propofol and sevoflurane regarding with the direct anaesthetic effects on cancer malignancy and the indirect effects on host immunity in a cancer xenograft mode of mice. Cultured colon cancer cell (Caco-2) was injected subcutaneously to nude mice (day 1). Mice were exposed to either 1.5% sevoflurane for 1.5 h or propofol (20 μg g-1; ip injection) with or without 4 μg g-1 lipopolysaccharide (LPS; ip) from days 15 to 17, compared with those without anaesthetic exposure as controls. The clinical endpoints including tumour volumes over 70 mm3 were closely monitored up to day 28. Tumour samples from the other cohorts were collected on day 18 for PCR array, qRT-PCR, western blotting and immunofluorescent assessment. Propofol treatment reduced tumour size (mean ± SD; 23.0 ± 6.2mm3) when compared to sevoflurane (36.0 ± 0.3mm3) (p = 0.008) or control (23.6 ± 4.7mm3). Propofol decreased hypoxia inducible factor 1α (HIF1α), interleukin 1β (IL1β), and hepatocyte growth factor (HGF) gene expressions and increased tissue inhibitor of metalloproteinases 2 (TIMP-2) gene and protein expression in comparison to sevoflurane in the tumour tissue. LPS suppressed tumour growth in any conditions whilst increased TIMP-2 and anti-cancer neutrophil marker expressions and decreased macrophage marker expressions compared to those in the LPS-untreated groups. Our data indicated that sevoflurane increased cancer development when compared with propofol in vivo under non-surgical condition. Anaesthetics tested in this study did not alter the effects of LPS as an immune modulator in changing immunocyte phenotype and suppressing cancer development.

[PMID: 37513937 PMCID: PMC10383422 DOI: 10.3390/ph16071026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 06/25/2023] [Accepted: 07/04/2023] [Indexed: 07/30/2023] Open
Abstract
Colorectal cancer (CRC) is the third most frequent cancer and the second leading cause of cancer-related deaths globally. Evidence shows that over 90% of CRC cases are initiated by a deregulated Wingless Integrated Type-1 (WNT)/β-catenin signaling pathway. The WNT/β-catenin pathway also promotes CRC cell proliferation, stemness, and metastasis. Therefore, modulators of the WNT/β-catenin pathway may serve as promising regimens for CRC. This study investigated the effect of cryptolepine-a plant-derived compound-on the WNT/β-catenin pathway in CRC. Two CRC cell lines, COLO205 and DLD1, were treated with cryptolepine or XAV 939 (a WNT inhibitor) in the presence or absence of WNT3a (a WNT activator). Using a tetrazolium-based assay, cryptolepine was found to reduce cell viability in a dose- and time-dependent manner and was a more potent inhibitor of viability than XAV 939. RT-qPCR analyses showed that cryptolepine reverses WNT3a-induced expression of β-catenin, c-MYC, and WISP1, suggesting that cryptolepine inhibits WNT3a-mediated activation of WNT/β-catenin signaling. Cryptolepine also repressed WNT3a-induced OCT4 and CD133 expression and suppressed colony formation of the cells, indicating that cryptolepine inhibits the stemness of CRC cells. Additionally, cryptolepine inhibited WNT3a-induced epithelial-to-mesenchymal transition by reducing the expression of SNAI1 and TWIST1 genes. In a wound healing assay, cryptolepine was found to suppress cell migration under unstimulated and WNT3a-stimulated conditions. Moreover, cryptolepine downregulated WNT3a-induced expression of MMP2 and MMP9 genes, which are involved in cancer cell invasion. Altogether, cryptolepine suppresses CRC cell proliferation, stemness, and metastatic properties by inhibiting WNT3a-mediated activation of the WNT/β-catenin signaling pathway. These findings provide a rationale for considering cryptolepine as a potential WNT inhibitor in CRC.

[PMID: 36204131 PMCID: PMC9532081 DOI: 10.1155/2022/7357160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Accepted: 08/30/2022] [Indexed: 11/17/2022]
Abstract
Objective The aim of the study is to explore the relationship between matrix metalloproteinase 2 (MMP-2) and matrix metalloproteinase 9 (MMP-9) gene polymorphisms and the risk of colorectal cancer. Methods From January 2019 to December 2021, 308 patients with colorectal cancer in our hospital were selected to be included in the colorectal cancer group and 300 normal healthy people were included in the control group. We perform genotyping, compare the genotype frequencies between the colorectal cancer group and the control group, calculate the relationship between MMP-2 and MMP-9 gene polymorphisms and disease risk, and analyze the genotype distribution characteristics of colorectal cancer patients with different pathological stages and lymph node metastasis status. The expression levels of serum MMP-2 and MMP-9 in patients with different genotypes were compared. Results The frequency of CC genotype and C gene at the MMP-2 gene−735 (C/T) locus in the colorectal cancer group was higher than that of the control group, and the frequency of TT genotype and T gene at MMP-9 gene−1562 (C/T) locus was a higher control group (P < 0.05). The comparison of genotype and gene frequency distribution of MMP-2 gene−1306 (C/T), −790 (T/G), and MMP-9 gene R668Q and P574R between the colorectal cancer group and the control group (P > 0.05); MMP-2 gene−735 (C/T) locus CC genotype and MMP-9 gene−1562 (C/T) locus TT genotype are dangerous genotypes for colorectal cancer. OR values were 1.490 (95% CI: 1.085–2.047), 1.519 (95% CI: 1.061–2.174); TNM stage III-IV, the proportion of CC genotype and TT genotype at MMP-9 gene−1562 (C/T) locus in patients with lymph node metastasis is higher than that without lymph node metastasis of TNM stage I-II patients (P < 0.05); MMP-2 gene in colorectal cancer patients. Serum MMP-2 levels in patients with CC genotype at 735 (C/T) locus were higher than those with CT + TT genotype, and serum MMP-9 levels in patients with TT genotype at MMP-9 gene−1562 (C/T) locus were higher CT + CC genotype patients (P < 0.05). Conclusion The CC genotype at −735 (C/T) locus of the MMP-2 gene and the TT genotype at−1562 (C/T) locus of the MMP-9 gene are risk genotypes for the development of colorectal cancer.

TIMP-2 regulates 5-Fu resistance via the ERK/MAPK signaling pathway in colorectal cancer. Aging (Albany NY) 2022; 14:297-315. [PMID: 35022331 PMCID: PMC8791226 DOI: 10.18632/aging.203793] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 12/03/2021] [Indexed: 12/24/2022]
Abstract
5-Fluorouracil (5-Fu) is the first-line chemotherapeutic option for colorectal cancer. However, its efficacy is inhibited by drug resistance. Cytokines play an important role in tumor drug resistance, even though their mechanisms are largely unknown. Using a cytokine array, we established that tissue inhibitor metalloproteinase 2 (TIMP-2) is highly expressed in 5-Fu resistant colorectal cancer patients. Analysis of samples from 84 patients showed that elevated TIMP-2 expression levels in colorectal patients were correlated with poor prognostic outcomes. In a 5-Fu-resistant patient-derived xenograft (PDX) model, TIMP-2 was also found to be highly expressed. We established an autocrine mechanism through which elevated TIMP-2 protein levels sustained colorectal cancer cell resistance to 5-Fu by constitutively activating the ERK/MAPK signaling pathway. Inhibition of TIMP-2 using an anti-TIMP-2 antibody or ERK/MAPK inhibition by U0126 suppressed TIMP-2 mediated 5-Fu-resistance in CRC patients. In conclusion, a novel TIMP-2-ERK/MAPK mediated 5-Fu resistance mechanism is involved in colorectal cancer. Therefore, targeting TIMP-2 or ERK/MAPK may provide a new strategy to overcome 5-Fu resistance in colorectal cancer chemotherapy.

Abstract
As the commonest type of cancer in Europe and the third most common type of cancer worldwide, colorectal carcinoma (CRC) poses a challenge for numerous scientific studies. At present, the cause of this disease is remains to be elucidated, but early diagnosis is only one solution to prevent serious health complications. As a structural scaffold, the extracellular matrix (ECM) is in direct contact with tumour cells and significantly interferes with tumour progression. During the process of tumorigenesis, the ECM undergoes structural changes in which collagens serve an important role. Their life cycle is regulated by proteolytic enzymes called matrix metalloproteinases (MMPs), which are controlled by tissue inhibitors of metalloproteinases (TIMPs). The present study analysed the gene expression of MMPs (MMP1-2-8-10-13), TIMPs (TIMP1-2-4) and collagens (COL1A1 and COL3A1) and the correlation with biochemical parameters in the adjacent rectal tissue (ART) of patients with CRC. The patients who underwent standard neoadjuvant pre-therapy showed increased concentrations of collagen in the normal ART. The mRNA levels of COL3A1, TIMP1 and TIMP2 were significantly higher in the ART of CRC patients (with or without pre-therapy) when compared with the control group. This finding suggested that TIMPs served an important role in the regulation of MMPs and in the modification of collagen content in the ECM. Despite the small data set, the present study provided insights into the transcriptomic relationships between the individual genes that are an integral part of the ECM.

Abstract
Simple Summary Colorectal cancer (CRC) is one of the most common cancer worldwide. CRC is derived from polyps and many factors, such as Matrix Metalloproteinases (MMPs) can gain the progression of colorectal carcinogenesis. Many investigations have indicated the role of MMPs in CRC development while there is not enough knowledge about the function of MMPs in precancerous conditions. This review summarizes the current information about the role of MMPs in polyps and CRC progression. Abstract Colorectal cancer (CRC) is the third and second cancer for incidence and mortality worldwide, respectively, and is becoming prevalent in developing countries. Most CRCs derive from polyps, especially adenomatous polyps, which can gradually transform into CRC. The family of Matrix Metalloproteinases (MMPs) plays a critical role in the initiation and progression of CRC. Prominent MMPs, including MMP-1, MMP-2, MMP-7, MMP-8, MMP-9, MMP-12, MMP-13, MMP-14, and MMP-21, have been detected in CRC patients, and the expression of most of them correlates with a poor prognosis. Moreover, many studies have explored the inhibition of MMPs and targeted therapy for CRC, but there is not enough information about the role of MMPs in polyp malignancy. In this review, we discuss the role of MMPs in colorectal cancer and its pathogenesis

Abstract
INTRODUCTION Diverticulosis affects approximately 60% of population after 60th year of age. Diverticular disease is symptomatic diverticulosis characterized by abdominal pain, flatulence and bloating, and bowel habits change. Age and lifestyle are risk factors for diverticulosis, additionally genetic predisposition is postulated. The aim of the study was to assess whether tissue inhibitors of matrix metalloproteinase (TIMP) 1 rs4898 and TIMP2 rs8179090 genetic variants are related to colonic diverticulosis. METHODS The study included 220 patients, 100 with colon diverticulosis diagnosed on colonoscopy and 120 controls. TIMP1 rs4898 and TIMP2 rs8179090 variants were examined using PCR-restriction fragments length polymorphism from a blood sample. RESULTS Allele T of TIMP1 rs4898 was more frequent in male patients with diverticulosis than in controls (P < 0.01), whereas in women there were no differences in its distribution, both in heterozygotes and homozygotes or in homozygotes separately, proving a recessive effect. TIMP2 s8179090 allele G frequency was 0.95 in cases and controls, there were no CC homozygotes identified, and no associations with diverticulosis showed. CONCLUSION TIMP1 rs4898 allele T may be a genetic determinant of the risk of diverticulosis in men.

Abstract
Tumor metastasis is a major cause of death of patients with colorectal cancer (CRC). Our previous findings show that adenine has antiproliferation activity against tumor cells. However, whether adenine reduces the invasiveness of DLD-1 and SW480 CRC cells has not been thoroughly explored. In this study, we aimed to explore the effects of adenine on the invasion potential of DLD-1 cells. Our findings showed that adenine at concentrations of ≤200 μM did not influence the cell viability of DLD-1 and SW480 CRC cells. By contrast, adenine reduced the migratory potential of the CRC cells. Moreover, it decreased the invasion capacity of the CRC cells in a dose-dependent manner. We further observed that adenine downregulated the protein levels of tissue plasminogen activator, matrix metalloproteinase-9, Snail, TWIST, and vimentin, but upregulated the tissue inhibitor of metalloproteinase-1 expression in DLD-1 cells. Adenine decreased the integrin αV level and reduced the activation of integrin-associated signaling components, including focal adhesion kinase (FAK), paxillin, and Src in DLD-1 cells. Further observations showed that adenine induced AMP-activated protein kinase (AMPK) activation and inhibited mTOR phosphorylation in DLD-1 cells. The knockdown of AMPK restored the reduced integrin αV level and FAK/paxillin/Src signaling inhibited by adenine in DLD-1 cells. Collectively, these findings reveal that adenine reduces the invasion potential of DLD-1 cells through the AMPK/integrin/FAK axis, suggesting that adenine may have anti-metastatic potential in CRC cells.

Abstract
Matrix metalloproteinases (MMPs) are a family of zinc-dependent metalloendopeptidases that degrades extracellular matrix (ECM) components. MMPs are associated with venous wall remodelling, proliferation, migration, phenotypic and functional transformation of vascular smooth muscle cells and ECM organization under the physiological and pathophysiological conditions. We investigated possible association of genetic promoter polymorphisms of MMP2 (rs243866), MMP8 (rs11225395), MMP9 (rs3918242) and TIMP2 (rs8179090) to varicose veins development in the Slovak population. Genomic DNA from 276 Slovak individuals (138 cases, 138 controls) was genotyped for selected SNPs (rs243866, rs11225395, rs3918242 and rs8179090) using the PCR-RFLP analysis. The data were analysed by chi-squared (chi2) test, logistic regression, and Mann-Whitney test. The risk of varicose veins development was evaluated in dominant, codominant and recessive genetic models. The statistical evaluation of selected polymorphisms in patients in all three genetic models has not shown a significant risk of varicose veins development. Our study has not shown the association between selected polymorphisms and increased risk of varicose veins development in Slovak population. More evidence with broaden sample size is needed.

Abstract
Okra flowers contain a higher content of total flavonoids than most other flowers; however little research has been conducted on their potential benefits, including antitumor activity. In this study, we extracted and purified flavonoids from okra flower (AFE), and aimed to evaluate the effect of AFE and its underlying mechanism on colorectal cancer (CRC) cell growth in vitro and in vivo. Here, we identify that AFE is a safe, natural antioxidant and exerts significant antitumor efficacy on the inhibition of CRC cell proliferation and metastasis as well as tumour growth in vivo. We further reveal that AFE inhibits CRC cell proliferation by inducing mitochondrial dysfunction, which results from the activation of p53 and induction of apoptosis and senescence, and inhibits autophagic degradation. Furthermore, AFE inhibited migration and invasion of CRC cells by regulating the balance of MMP2/TIMP2 and MMP9 expression levels. Of note, administration of AFE as a preventive agent achieves a more effective antitumor effect than the therapeutic agent in a xenograft mouse model. Our results reveal, for the first time, that AFE is a safe, natural antioxidant with significant antitumor efficacy, which has great potential in the application for CRC prevention and treatment.

Abstract
Colorectal cancer (CRC) is the third most common cancer worldwide. This study aimed to explore the regulatory mechanisms of miRNAs in CRC. Differentially expressed miRNAs (DEMs) and differentially expressed genes (DEGs) in CRC tissue samples compared with control samples in mRNA and miRNA datasets were screened. Functional and pathway enrichment analysis of the DEGs was carried out. Targets of the DEMs were identified. Overlaps between the DEGs and targets of DEMs were selected. The miRNA-mRNA regulatory network of these overlaps was constructed and visualized. The candidate genes selected were validated by quantitative real-time PCR. DEGs were identified and considered DEGs-1 and DEGs-2. A total of 584 genes in DEGs-1 and 527 genes in DEGs-2 were obtained, including 465 overlaps, and 44 DEMs were identified. The overlaps were enriched in 46 Gene Ontology terms and 19 Kyoto Encyclopedia of Genes and Genomes pathways. Moreover, 137 overlapped genes between targets of the DEMs and the 465 overlaps were obtained. The miRNA-mRNA regulating network of the 137 overlapped genes was constructed. Extracellular matrix-related proteins and pathways might play critical roles in the development of CRC. The quantitative real-time PCR results of the candidates were in agreement with the bioinformatics analysis. miR-128, miR-182, and miR-143 might be key miRNAs regulating cell proliferation and metastasis of CRC.

Abstract
Colorectal cancer has a common cause of morbidity and mortality. Therefore, it is urgent to detect reliable biomarkers to predict prognosis in CRC. Here, we determined the expression of TIMP-2 and MMP-9 in a CRC tissue microarray by immunohistochemistry. We found that lower TIMP-2 or/and higher MMP-9 expression in cancer tissues was correlated with poorer overall survival (OS). TIMP-2 or MMP-9 expression was independent prognostic factors for CRC. Furthermore, TIMP-2 and MMP-9 expression had a synergistic role as efficient prognostic indicators for CRC patients. In vitro and in vivo, TIMP-2 could inhibit HCT 116 cells invasion and migration by regulating MMP-9. In sum, a combined expression of TIMP-2 and MMP-9 as efficient prognostic indicators was found for the first time.

Abstract
Stanniocalcin 2 (STC2), a secretory glycoprotein hormone, regulates many biological processes including cell proliferation, apoptosis, tumorigenesis and atherosclerosis. However, the effect of STC2 on proliferation, migration and epithelial-mesenchymal transition (EMT) progression in human colorectal cancer (CRC) cells remains poorly understood. The expression level of STC2 was determined by quantitative real-time polymerase chain reaction (qPCR) and western blot analysis. Cell Counting Kit-8 (CCK-8) was used to detect the viability of SW480 cells. The invasion and migration of cells were identified by wound healing and Transwell assays. The mRNA and protein expression levels of β-catenin, matrix metalloproteinase (MMP)-2, MMP-9, E-cadherin and vimentin were assessed by qPCR and western blot analysis. In the present study, it was demonstrated that STC2 was highly expressed in the CRC cell lines. After silencing of STC2, the cell viability, migration and invasion were significantly reduced. Silencing of STC2 in the CRC Sw480 cells increased the expression of E-cadherin and decreased the expression of vimentin, MMP-2 and MMP-9, compared to those in the normal and empty vector group. Furthermore, the expression of β-catenin in the STC2 gene silenced group was suppressed, and the expression of β-catenin was reversed by Wnt activator, SB216763. These results demonstrated that STC2 participates in the development and progression of CRC by promoting CRC cell proliferation, survival and migration and activating the Wnt/β-catenin signaling pathway.

Abstract
BACKGROUND TIMP-2 gene plays an important role in the development of breast cancer. The present study was conducted to evaluate whether TIMP-2 gene polymorphisms are associated with breast cancer risk in a Han Chinese cohort. METHODS Six single nucleotide polymorphisms (SNPs) within the TIMP-2 gene in 571 breast cancer and 578 healthy control subjects were genotyped through the Agena MassARRAY. Logistic regression analysis was used to assess the influence of TIMP-2 polymorphisms on breast cancer. Functional annotation of TIMP-2 variants and TIMP-2 expression were analyzed by bioinformatics. RESULTS Bioinformatics analysis found that rs4789936 was likely to affect transcription factor binding, motifs, DNase footprint, and DNase peaks; and TIMP-2 was under-expressed in breast cancer, the risk allele of rs4789936 was associated with increased expression of TIMP-2 in peripheral blood samples. Importantly, individuals carrying TIMP-2 rs2277698 T allele have a 19% lower risk of breast cancer than individuals with allele C, providing protection (OR = 0.81, 95%CI = 0.67-0.99, p = 0.041). In the breast cancer patients with c-erb positive and PR positive, when the CC genotype was used as a reference, individuals carrying the TT genotype increased the risk of breast cancer. Haplotype analysis showed "TCC" was associated with a reduced risk of breast cancer (OR = 0.79, 95%CI = 0.63-0.97, p = 0.028). CONCLUSION Our study indicated that TIMP-2 rs2277698 was associated with breast cancer susceptibility.

Biosci Rep 2019; 39:BSR20190478. [PMID: 30988064 PMCID: PMC6509169 DOI: 10.1042/bsr20190478] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 04/02/2019] [Accepted: 04/08/2019] [Indexed: 12/28/2022] Open
Abstract
Background: The tissue inhibitors of metalloproteinases (TIMPs) including TIMP2 and TIMP3 are the key physiological inhibitors of matrix metalloproteinases (MMPs) and along with MMPs, TIMPs play a vital role in the coordinated proteolytic breakdown and remodeling of the extracellular matrix (ECM) and the basement membrane that represent the barriers to any malignant tumor invasion and progression. These enzymes are vital for tumor invasion and metastasis and also play a critical role in several other stages of tumor development and progression. The studies on the association of various polymorphisms in human TIMP2 and TIMP3 genes including TIMP2-418G/C and TIMP3-1296T/C single nucleotide polymorphisms (SNPs) and CRC risk are limited, mixed, and inconclusive.Materials and methods: The aim of the present study was to analyze the association of TIMP2-418G/C and TIMP3-1296T/C promoter SNPs with colorectal cancer (CRC) susceptibility and development risk and also to evaluate the modifying effects of possible TIMP2-418G/C and TIMP3-1296T/C SNPs' genotypes on different risk factors of CRC or the reciprocal effect in ethnic population of Kashmir, India through a case-control setup. The genotype frequencies of TIMP2-418G/C and TIMP3-1296T/C promoter SNPs were compared between 142 CRC patients and 184 individually matched healthy controls by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The associations between the TIMP2-418G/C and TIMP3-1296T/C SNPs and CRC risk were examined through conditional logistic regression models adjusted for multiple possible confounding (third) variables. The possible effect measure modification of the association between the relevant SNP genotypes and CRC risk by various CRC risk factors including age, gender, and smoking status was also analyzed. Further, the associations between these SNPs and various clinico-pathological parameters, demographic variables, and environmental factors within the case group subjects with regard to CRC risk were also evaluated.Results: The overall association between the TIMP2-418G/C and TIMP3-1296T/C SNPs and the modulation of CRC risk was found to be highly significant (P=0.019 and P=0.000 for TIMP2 and TIMP3 SNPs, respectively). The heterozygous genotype (GC) of TIMP2-418G/C was significantly associated with an increased risk of colorectal cancer [OR, 1.87 (95%CI, 1.07-3.27); P=0.027] whereas the heterozygous genotype (TC) of TIMP3-1296T/C SNP was significantly associated with a decreased risk of colorectal cancer [OR, 0.53 (95%CI, 0.32-0.86); P=0.011]. The variant genotype (CC) of TIMP3-1296T/C SNP was also significantly associated with a decreased risk of colorectal cancer [OR, 0.18 (95%CI, 0.05-0.65); P=0.009].Conclusion: The present study demonstrates that there is a strong and highly significant association between the TIMP2-418G/C and TIMP3-1296T/C promoter SNPs and the risk of developing CRC in ethnic Kashmiri population. However, in order to substantiate our findings, the present study needs to be replicated with bigger sample size and should involve other ethnically defined populations with high CRC risk.

Zhou S, Xu J. Downregulation of microRNA-204 increases the expression of matrix metallopeptidase 9 in pediatric patients with pulpitis and Helicobacter pylori infection in the stomach. Exp Ther Med 2019; 18:253-259. [PMID: 31258660 DOI: 10.3892/etm.2019.7528] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2017] [Accepted: 03/26/2019] [Indexed: 12/18/2022] Open
Abstract
The present study examined the expression of microRNA (miRNA or miR)-204 in pulp tissues, blood and saliva from pediatric patients with pulpitis and an underlying Helicobacter pylori (Hp) infection in the stomach, and the mechanism of the associated regulation by miR-204 was assessed. A total of 26 children with pulpitis who received tooth extraction at the Children's Hospital of Nanjing Medical University (Nanjing, China) between December 2014 and August 2016 were diagnosed with Hp infection in the stomach and included in the present study (HP+ group); furthermore, 19 children with pulpitis but without Hp infection in the stomach were enrolled as a control (HP- group). Pulp tissues, blood (serum) and saliva samples were collected from all subjects. Reverse-transcription quantitative polymerase chain reaction was used to determine the expression of miR-204 and matrix metalloproteinase 9 (MMP9) mRNA. Western blot analysis was performed to determine MMP9 protein expression in pulp tissues, while ELISA was performed to measure the contents of MMP9 in serum and saliva. A dual luciferase reporter assay was used to identify the direct interaction between miR-204 and its target protein. The results indicated that Hp infection in the stomach was associated with an upregulation of MMP9 mRNA and protein in pulp tissues, serum and saliva from children with pulpitis. Furthermore, the levels of miR-204 in pulp tissues, serum and saliva from children with pulpitis and Hp infection in the stomach were significantly reduced. miR-204 was confirmed to regulate the expression of MMP9 by directly binding with the 3'-untranslated region of MMP9 mRNA. The present study demonstrated that MMP9 expression in pulp tissues, blood and saliva from children with pulpitis and Hp infection in the stomach was upregulated, while miR-204 expression was downregulated. miR-204 may affect inflammatory processes and other oral diseases in children with pulpitis and Hp infection via MMP9, and may be a potential marker for the detection of Hp infection in children with pulpitis.

MnTE-2-PyP Attenuates TGF- β-Induced Epithelial-Mesenchymal Transition of Colorectal Cancer Cells by Inhibiting the Smad2/3 Signaling Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:8639791. [PMID: 30931081 PMCID: PMC6410463 DOI: 10.1155/2019/8639791] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Accepted: 01/09/2019] [Indexed: 11/18/2022]
Abstract
Background As a key step in enhancing cancer cell invasion and metastasis, epithelial-mesenchymal transition (EMT) plays an important role in colorectal cancer progression. EMT is triggered by a variety of signaling pathways, among which the transforming growth factor β (TGF-β) signaling pathway has been implicated as a primary inducer. Accumulating evidence demonstrates that MnTE-2-PyP (chemical name: manganese(III) meso-tetrakis-(N-ethylpyridinium-2-yl), a superoxide dismutase (SOD) mimetic, inhibits TGF-β signaling; however, its ability to inhibit TGF-β-induced EMT in colorectal cancer has not yet been explored. Methods To verify our hypothesis that MnTE-2-PyP attenuates TGF-β-induced EMT, human colorectal cancer cells were treated with TGF-β in the presence or absence of MnTE-2-PyP. Cells were analyzed by several techniques including western blotting, real-time quantitative PCR, transwell assay, and wound healing assay. Results MnTE-2-PyP reverses cell phenotypes induced by TGF-β in colon cancer cells. MnTE-2-PyP treatment significantly reduced the expression of mesenchymal markers but maintained epithelial marker expression. Mechanistically, MnTE-2-PyP suppressed the phosphorylated Smad2/3 protein levels induced by TGF-β in SW480 cells, but MnTE-2-PyP failed to suppress TGF-β-induced Slug and Snail expression in colorectal cells. Furthermore, MnTE-2-PyP effectively suppressed TGF-β-mediated cell migration and invasion and the expression of matrix metalloproteinase 2 (MMP-2) and matrix metalloproteinase 9 (MMP-9) in colorectal cells. Conclusion Taken together, we provide an in-depth mechanism by which MnTE-2-PyP inhibits colorectal cancer progression, supporting an important role for MnTE-2-PyP as an effective and innovative antitumor agent to enhance treatment outcomes in colorectal cancer.

Abstract
PURPOSE Numerous studies have estimated the association between matrix metalloproteinases (MMPs) polymorphisms and the risk of oral cancer; the results, however, are inconsistent and conflicting. Therefore, we conducted a meta-analysis to evaluate the association of MMP-1, 2, and 3 polymorphisms with oral cancer risk. METHODS A computerized literature search was conducted of electronic databases and search engines. Odds ratios (OR) and 95% confidence intervals (CI) were calculated for each gene, and the heterogeneity among studies was estimated using the Q-test and I2 values. Overall and subgroup analyses were undertaken. Statistical analyses were conducted using Review Manager v5.3 and Stata v12.0 software. RESULTS Eighteen studies were included in this meta-analysis. For MMP-1(-1607) 1G/2G, a significant association was observed using the recessive genetic model (OR = 1.47; 95% CI = 1.14-1.91; I2 = 64%, pheterogeneity = 0.003). In the subgroup studies, a significant association was observed in the Asian subgroup (OR = 1.68; 95% CI = 1.42-1.99; I2 = 17%, pheterogeneity = 0.30 for the recessive model; and OR = 1.59; 95% CI = 1.19-2.13; I2 = 80%, pheterogeneity < 0.00001 for the allelic contrast model) and in the European subgroup (OR = 0.65; 95% CI = 0.44-0.98; I2 = 21%, pheterogeneity = 0.26 for the allelic contrast model). No significant associations were observed with either MMP-2(-1306) C/T or MMP-3(-1171) 5A/6A. CONCLUSIONS The MMP-1(-1607) 1G/2G polymorphism is associated with oral cancer risk, and the 2G allele played different roles in Asian and European populations.

Abstract
Matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) involve in the degradation of the extracellular matrix (ECM) that imbalances their activity and may lead to various diseases. The present study aims to evaluate the association between MMP9-1562C/T and TIMP2-418G/C variants and synergistic effects of both variants on male infertility in an Iranian population. We analyzed these polymorphisms in 101 infertile men and 106 fertile men as a control group using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Based on the obtained results, no considerable association was observed in MMP9-1562C/T polymorphism frequency between infertile men and controls while frequencies of TIMP2-418G/C variant were significantly different in infertile and control groups (P = 0.028). Men with CC, GC and CC + GC genotypes for TIMP2-418G/C polymorphism had an increased risk of infertility compared to men with GG genotype [OR = 1.85, 95% CI (0.917-3.734, P = 0.086), OR = 1.94, 95% CI (1.098-3.437, P = 0.023) and OR = 2.053 95% CI (1.179-3.577, P = 0.011), respectively]. Also, in the presence of both TIMP2-418C and MMP9-1562T alleles the male infertility risk was significantly increased (P = 0.032). The current study suggests that the variation of TIMP2 gene and its interaction with MMP9 gene might be associated with male infertility. However, to confirm these findings, further studies are required in different ethnicities and with a larger sample size.

Abstract
The aim of the present study was to identify potential biomarkers associated with colorectal cancer (CRC). The GSE32323 and GSE53592 mRNA and microRNA (miRNA) expression profiles were selected from the Gene Expression Omnibus database. The differentially expressed genes (DEGs) and differentially expressed miRNAs (DEMs) in CRC tissue samples compared with surrounding control tissue samples (DEGs‑CC), and DEGs in cells treated with 5‑aza‑2'‑deoxycitidine compared with untreated cells (DEGs‑TC) were identified with the Limma package. The Database for Annotation, Visualization and Integrated Discovery was used to conduct the functional and pathways enrichment analysis. Differential co‑regulation networks were constructed using the DCGL package of R. The targets of DEMs were identified using TargetScan. The overlaps between DEGs and the targets were selected. The miRNA‑gene regulatory network of the overlaps was established. There were 145 DEMs, and 1,284 DEGs in DEGs‑CC, and 101 DEGs in DEGs‑TC. DEGs‑CC were enriched in 196 Gene Ontology (GO) terms and 23 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. DEGs‑TC were enriched in 46 GO terms and two KEGG pathways. A differential co‑regulation network of the DEGs and a miRNA‑gene regulatory network between DEMs and overlapped DEGs were respectively constructed. miR‑124‑3p, miR‑145‑5p and miR‑320a may be critical in CRC, and serum/glucocorticoid regulated kinase 1 and SRY‑box 9 may be potential biomarkers for CRC tumor progression.

Abstract
To explore the prognostic related factors and mechanisms of gastric cancer (GC), we performed the systematic analysis with integrated bioinformatics tools based on multiple on-line datasets. With uni-variate COX analysis, we screened out 37 survival hazardous genes in GC. Further GO assays disclosed that the signatures related with extracellular matrix and structure, and the functions of "cell adhesion molecule binding" and "integrin binding" were the vital mechanisms of disease progression, and tissue inhibitor of metalloproteinase-2 (TIMP2) was the potential biomarker for prognosis. Based on GSEA, GSVA and GCN, TIMP2 was demonstrated to interact with multiple integrin pathways and involve in the regulation of EMT, cell adhesion, and angiogenesis of GC. The associations of TIMP2 expression with reduced OS and RFS of patients were declared by Kaplan-Meier analysis, and further confirmed by 1000 internal bootstrap replications and external KM plotter analysis. With multi-variate COX regression and time-dependent ROC analysis, we validated the prediction independency and capacity of TIMP2 for prognosis. The relationships of TIMP2 with clinicopathological characteristics were also uncovered. Taken together, our findings identify TIMP2 as the novel candidate biomarker for poorer outcome of GC patients, and revealed the underlying functions of TIMP2 and the potential mechanisms for GC progression.

Abstract
PURPOSE Matrix metalloproteinases (MMPs) play important roles in tumorigenesis. The variant in MMP-9 -1562 C/T (single nucleotide polymorphisms labeled rs3918242) has been extensively evaluated as predisposing factors to digestive cancers susceptibility. However, most of these studies only contained a small number of subjects and they showed conflicting results. Therefore, to elucidate these associations, we carried out a large-scale meta-analysis to provide this accurately comprehensive synopsis of case-control studies. METHODS A comprehensive literature search was conducted in EMBASE, OVID, Medline, China National Knowledge Internet and Wanfang for relevant data published between Jan 2000 and Mar 2018. Overall and stratified analyses based on the cancer types, ethnicity and source of control were carried out. Odds ratios (ORs) correspondent to 95% confidence intervals (95% CIs) were calculated to evaluate the genetic correlation between the variant and digestive cancer susceptibility. Review Manager 5.2 and Stata 12.0 were used for statistical analysis. RESULTS Twenty studies containing 3201 digestive cancer patients and 4301 matched-controls were screened out. The overall results suggested that MMP-9 -1562 C/T polymorphism increased the susceptibility to digestive cancers under homozygote and recessive models (homozygote, OR = 1.35, 95% CI 1.00-1.82, P = 0.05; recessive, OR = 1.42, 95% CI 1.07-1.88, P = 0.02). Furthermore, in the subgroup analysis based on the source of control, similar conclusions were obtained in the population-based control subgroup (homozygote, OR = 1.63, 95% CI 1.16-2.27, P = 0.004; recessive, OR = 1.67, 95% CI 1.22-2.28, P = 0.001), but not in the hospital-based control. In subgroup analyses based on cancer types and ethnicity, no association was observed. CONCLUSIONS Our meta-analysis suggested that MMP-9 -1562 C/T polymorphism might be related to the digestive cancer susceptibility. Evidence with adequate sample size is needed.

Xiao K, Ouyang Z, Tang HH. Inhibiting the proliferation and metastasis of hilar cholangiocarcinoma cells by blocking the expression of vascular endothelial growth factor with small interfering RNA. Oncol Lett 2018; 16:1841-1848. [PMID: 30008874 DOI: 10.3892/ol.2018.8840] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2017] [Accepted: 04/15/2018] [Indexed: 12/13/2022] Open
Abstract
The aim of the present study was to investigate whether the proliferation and metastasis of hilar cholangiocarcinoma cells can be suppressed and whether apoptosis can be induced by small interfering RNA (siRNA) repression of vascular endothelial growth factor (VEGF). siRNA sequences targeting the VEGF gene were designed and the human hilar cholangiocarcinoma QBC939, HCCC-9810 and RBE cell lines were transfected with VEGF-siRNA plasmids for 48 h. Reverse transcription-quantitative polymerase chain reaction and western blotting measured the levels of VEGF-A, VEGF-C and matrix metalloproteinase 2 (MMP2) mRNA expression and protein content. The cell invasion potential was evaluated using the Transwell invasion and migration assay and the MTT assay was employed to detect the proliferation of hilar cholangiocarcinoma cells. Flow cytometry was used to quantify cell apoptosis and necrosis. Following the transfection of VEGF-siRNA, a significant reduction of mRNA and protein levels of VEGF-A, VEGF-C and MMP2 was observed in the hilar cholangiocarcinoma cells. The invasion, migration and proliferation of tumor cells were also notably decreased. The rate of tumor cell apoptosis was increased in the VEGF-siRNA group (15.42%) compared with the non-siRNA control (2.22%) and the negative control (2.71%) groups. It was concluded that blocking the expression of VEGF via VEGF-siRNA effectively inhibited the invasion, migration and proliferation, and induced apoptosis in hilar cholangiocarcinoma cells. These observations suggested that targeting VEGF with RNAi may be an effective therapeutic strategy for treating hilar cholangiocarcinoma.

Abstract
Angiogenesis (the growth of new blood vessels) is essential in most of the body’s physiological processes, such as in the normal functioning of the endometrium during and after the menstrual cycle. Vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP) are the mostly expressed angiogenic factors, especially, during the process of endometrial degeneration and remodeling. In carcinogenesis, tumor hypoxia-induced factors, through the process of “angiogenic switch”, stimulate the production of angiogenic factors, particularly VEGF and MMP. Subsequently, these angiogenic factors are associated with degradation, differentiation, proliferation, and migration of vascular endothelial cells, enhancing the formation of new blood vessels to supply the tumor with oxygen and nutrients. This process is equally significant for tumor development and metastasis. Hence, like in other cancers, the overexpression of MMP and VEGF in endometrial cancer (EC) seems to play a significant role in its tumorigenesis and metastasis. This research will discuss the influence of MMP and VEGF on angiogenesis, metastasis, and the prognosis of EC as well as the clinical importance of the factors in the diagnosis of EC.

Abstract
Tissue inhibitors of metalloproteinases (TIMPs) appear to affect many aspects of cancer biology, playing a crucial role in cell signaling by regulating cell growth, apoptosis, invasion, metastasis, angiogenesis, and genomic instability. In the present study, we investigate whether TIMP-2 SNP, TIMP-2 mRNAs, and TIMP-2 protein is associated with susceptibility to colorectal cancer (CRC) in Tunisian population. Taqman and DNA sequencing techniques were used for genotyping, TIMP-2 expression of each genotype was analyzed using semiquantitative RT-PCR and TIMP-2 protein expression was analyzed using immunohistochemistry staining. Our results showed that significantly elevated CRC risk was found in individuals with CC genotype (odds ratio 1.959; 95% confidence interval, 1.055-3.637). Moreover TIMP-2 mRNA expression in the colorectal cell carcinomas was significantly higher compared with the normal colorectal tissue (0.487±0.015 vs. 0.210±0.013) (P<0.05). In addition, serum levels of TIMP-2 were significantly lower in CRC patients than in adenoma patients (P=0.01) and healthy controls (P=0.003). Serum levels of TIMP-2 correlated significantly with tumor stage and TNM stage and were the lowest in CRC patients with stage D,T4,(N1,N2,N3),M(+). In conclusion, our study demonstrate for the first time the distribution and the clinical significance of TIMP-2 promoter polymorphisms, mRNA, protein expression, and serum level in CRC Tunisian patients suggesting that the genotyping and serum level of TIMP-2 as potential markers for susceptibility to CRC will allow a precise and early identification of individuals at high risk and will aid the design of therapeutic modalities and evaluation of treatment outcome.

Abstract
Plants reputed to have cancer-inhibiting potential and putative active components derived from those plants have emerged as an exciting new field in cancer study. Some of these compounds have cancer-inhibiting potential in different clinical staging levels, especially metastasis. A few of them which stabilize cell-cell adhesions are controversial topics. This review article introduces some effective herbal compounds that target E-cadherin/β-catenin protein complex. In this article, at first, we briefly review the structure and function of E-cadherin and β-catenin proteins, Wnt signaling pathway, and its target genes. Then, effective compounds of the Teucrium persicum, Teucrium polium, Allium sativum (garlic), Glycine max (soy), and Brassica oleracea (broccoli) plants, which influence stability and cellular localization of E-cadherin/β-catenin complex, were studied. Based on literature review, there are some compounds in these plants, including genistein of soy, sulforaphane of broccoli, organosulfur compounds of garlic, and the total extract of Teucrium genus that change the expression of variety of Wnt target genes such as MMPs, E-cadherin, p21, p53, c-myc, and cyclin D1. So they may induce cell-cycle arrest, apoptosis and/or inhibition of Epithelial-Mesenchymal Transition (EMT) and metastasis.

Abstract
OBJECTIVES Matrix metalloproteinases (MMPs) play an important role in the pathogenesis of coronary artery disease (CAD). This study aims to determine the association of MMP-9 genotype polymorphisms and its serum levels with the risk of acute myocardial infarction (AMI) in Egyptian patients. Also, it evaluated their role as predictors of AMI outcome after six months follow-up. METHODS Subjects included in the study were 184 patients with AMI and 180 controls. Genotyping of MMP-9-1562C>T polymorphism was carried out by PCR-based restriction digestion method. Serum MMP-9 was measured using ELIZA assay. All patients were followed for AMI complications during their hospitalization and 6 months later on. RESULTS MMP-9-1562T allele was more frequent in patients than in controls (OR=1.65, 95%CI 1.09-2.15, P=0.011). the frequency of CT+TT genotypes were higher in patients with morbidity (OR=2.85, 95%CI 1.29-6.29, P=0.008) and with mortality (OR=3.21, 95%CI 1.28-8.02, P=0.012) than in those without MI complications. Serum MMP-9 levels were significantly elevated in AMI as compared to controls and more associated with TT genotype. The impairment of LV function (ΔEF, ΔLAD, ΔE/A) was more observed in the TT genotype compared with CC genotype. CONCLUSIONS Our data suggest that MMP-9 (TT genotype) and its serum level are associated with the risk of suffering AMI in Egyptians. In addition, MMP-9 polymorphism and its level might be useful clinical biomarkers for predicting the outcome of AMI.

Abstract
Proper function of the blood-testis barrier is pivotal to spermatogenesis. Synchronised action of matrix metalloproteinases (MMP) and their inhibitors (TIMP) is mandatory to maintain dynamic balance of the barrier. Therefore, the association of functional genetic variants of MMP-2, MMP-9 and TIMP-2 and male infertility was studied. A total of 416 infertile males and 421 healthy subjects were genotyped for 7 SNPs within MMP2, MMP9 and TIMP2 genes, along with the assessment of semen parameters (concentration, motility and morphology of spermatozoa). No association was observed between the studied genotypes and male infertility. However, higher sperm concentration was associated with TIMP2 rs8080623 C and rs2277698 T variants among infertile men, and with MMP9 rs17576 A minor allele in controls (p < .05). TIMP2 rs9900972 T and rs2277698 T allele were associated with higher percentage of morphologically normal spermatozoa among controls. MMP2 rs2285053 TT homozygous infertile patients presented higher percentage of spermatozoa displaying nonprogressive motility. Haplotype analysis revealed strong linkage disequilibrium between the studied loci (5 of 8 possible TIMP2 haplotypes, and 3 of 4 possible MMP2 and MMP9 were found). None of the haplotypes showed association with infertility. This study results suggest an association between MMP9 and TIMP2 SNPs with sperm parameters, but not infertility.

Abstract
Colorectal cancer (CRC) is a highly heterogeneous disease regarding the stage at time of diagnosis and there is special attention regarding adjuvant chemotherapy in unselected patients with stage I and stage II. The clinicohistologically based TNM staging system with emphasis on histological evaluation of primary tumor and resected regional lymph nodes remains the standard of staging, but it has restricted sensitivity resulting in false downward stage migration. Molecular characteristics might predispose tumors to a worse prognosis and identification of those enables identifying patients with high risk of disease recurrence. Suitable predictive markers also enable choosing the most appropriate therapy. The current challenge facing adjuvant chemotherapy in stages I and II CRC is choosing patients with the highest risk of disease recurrence who are going to derive most benefit without facing unnecessary adverse effects. Single nucleotide polymorphisms (SNPs) are one of the potential molecular markers that might help us identify patients with unfavorable prognostic factors regarding disease initiation and recurrence and could determine selection of an appropriate chemotherapy regimen in the adjuvant and metastatic setting. In this paper, we discuss SNPs of genes involved in the multistep processes of cancerogenesis, metastasis, and the metabolism of chemotherapy that might prove clinically significant.

Abstract
BACKGROUND Myeloproliferative disorders (MPDs) are clonal hematologic malignancies originating at the level of the pluripotent hematopoietic stem cell. Matrix metalloproteases (MMPs) are proteolytic enzymes that contribute to all stages of malignancy progression. Genetic variants in the MMP genes may influence the biological function of these enzymes and change their role in carcinogenesis and progression. To our knowledge, this is the first investigation of associations between the -735 C/T and -1562 C/T polymorphisms in the MMP2 and MMP9 genes, respectively, and the risk of essential thrombocytosis (ET), and polycythemia vera (PV). MATERIALS AND METHODS The case-control study included JAK2V617F mutation positive 102 ET and PV patients and 111 controls. Polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and electrophoresis. RESULTS No statistically significant differences were detected between patient (ET+PV) and control groups regarding genotype distribution for MMP2 gene-735 C/T and MMP9 gene -1562 C/T polymorphisms and C/T allele frequency (p>0.050). Statistically borderline significance was observed between PV and control groups regarding genotype distribution for the MMP9 gene -1562 C/T polymorphism (p=0.050, OR=2.26, 95%Cl=0.99-5.16). CONCLUSIONS Consequently this study supported that CC genotype of MMP9 gene -1562 C/T polymorphism may be related with PV even if with borderline significance.

Abstract
INTRODUCTION Matrix metalloproteinases (MMPs) are overexpressed at different stages of colorectal carcinogenesis and could serve as early surrogate biomarkers of colorectal neoplasia. OBJECTIVE To assess the utility of plasma MMP2 and MMP9 levels in the detection of advanced colorectal neoplasia and their correlation with tissue levels. METHODS We analysed blood and tissue samples from patients with non-advanced adenomas (n=25), advanced adenomas (n=25), colorectal cancer (n=25) and healthy controls (n=75). Plasma and tissue gelatinase levels were determined by Luminex XMAP technology and gelatin zymography. Receiver operating characteristic (ROC) curve analysis was used to calculate the optimum cut-off for the detection of advanced colorectal neoplasia. RESULTS Plasma MMP2 levels were similar between groups whatever the type of lesion. Plasma MMP9 levels were significantly higher in patients with neoplastic lesions than in healthy controls (median 292.3ng/ml vs. 139.08ng/ml, P<0.001). MMP9 levels were also higher in colorectal cancer than in non-advanced adenomas (median 314.6ng/ml vs. 274.3ng/ml, P=0.03). There was a significant correlation between plasma and tissue levels of MMP9 (r=0.5, P<0.001). The plasma MMP9 cut-off range with the highest diagnostic accuracy was between 173ng/ml and 204ng/ml (AUC=0.80 [95% CI: 0.72-0.86], P<0.001; sensitivity, 80-86% and specificity, 57-67%). CONCLUSION Plasma MMP9 could be a surrogate biomarker for the early detection of advanced colorectal neoplasia, although its diagnostic performance could be increased by combination with other biomarkers.

Abstract
Hepatocellular carcinoma (HCC) is one of the common malignancies, which is highly metastatic and the third common cause of cancer deaths in the world. The invasion and metastasis of cancer cells is a multistep and complex process which is mainly initiated by extracellular matrix (ECM) degradation. Aberrant expression of microRNA has been investigated in HCC and shown to play essential roles during HCC progression. In the present study, we found that microRNA-324-5p (miR-324-5p) was downregulated in both HCC cell lines and tissues. Ectopic miR-324-5p led to the reduction of HCC cells invasive and metastatic capacity, whereas inhibition of miR-324-5p promoted the invasion of HCC cells. Matrix metalloproteinase 2 (MMP2) and MMP9, the major regulators of ECM degradation, were found to be downregulated by ectopic miR-324-5p, while upregulated by miR-324-5p inhibitor. E26 transformation-specific 1 (ETS1) and Specificity protein 1 (SP1), both of which could modulate MMP2 and MMP9 expression and activity, were presented as the direct targets of and downregulated by miR-324-5p. Downregulation of ETS1 and SP1 mediated the inhibitory function of miR-324-5p on HCC migration and invasion. Our study demonstrates that miR-324-5p suppresses hepatocellular carcinoma cell invasion and might provide new clues to invasive HCC therapy.

Abstract
Epithelial ovarian cancer (EOC) is the most lethal of the gynecological malignancies. Exploring the molecular mechanisms and major factors of invasion and metastasis could have great significance for the treatment and prognosis of EOC. Studies have demonstrated that microRNA 106b (miR-106b) may be a promising therapeutic target for inhibiting breast cancer bone metastasis, but the role of miR-106b in EOC is largely unknown. In this work, miRNA-106b expression was quantified in various ovarian tissues and tumors. Ovarian carcinoma cell lines were transfected with miR-106b, after which, cell phenotype and expression of relevant molecules was assayed. Dual-luciferase reporter assays and xenograft mouse models were also used to investigate miR-106b and its target gene. MiR-106b mRNA expression was found to be significantly higher in normal ovarian tissues and benign tumors than in ovarian carcinomas and borderline tumors (p < 0.01), and was negatively associated with differentiation (Well vs. Por & Mod) and the International Federation of Gynecology and Obstetrics (FIGO) staging (stage I/II vs. stage III/IV) in ovarian carcinoma (p < 0.05). MiR-106b transfection reduced cell proliferation; promoted G1 or S arrest and apoptosis (p < 0.05); suppressed cell migration and invasion (p < 0.05); reduced Ras homolog gene family member C (RhoC), P70 ribosomal S6 kinase (P70S6K), Bcl-xL, Matrix metallopeptidase 2 (MMP2), MMP9 mRNA and protein expression; and induced p53 expression (p < 0.05). Dual-luciferase reporter assays indicated that miR-106b directly targets RhoC by binding its 3’UTR. MiR-106b transfection also suppressed tumor development and RhoC expression in vivo in xenograft mouse models. This is the first demonstration that miR-106b may inhibit tumorigenesis and progression of EOC by targeting RhoC. The involvement of miR-106b-mediated RhoC downregulation in EOC aggression may give extended insights into molecular mechanisms underlying cancer aggression. Approaches aimed at overexpressing miR-106b may serve as promising therapeutic strategies for treating EOC patients.

Abstract
The expression of microRNA-490-3P has been reported to regulate hepatocellular carcinoma cell proliferation, migration and invasion, and its overexpression significantly inhibits A549 lung cancer cell proliferation. Here, we demonstrated for the first time that miR-490 mRNA expression was significantly lower in ovarian carcinoma and borderline tumors compared to benign tumors, and lower in metastatic ovarian carcinoma (omentum) than primary ovarian carcinoma, and was negatively associated with differentiation and International Federation of Gynecology and Obstetrics (FIGO) staging. MiR-490-3P overexpression promoted G1/S or G2/M arrest and apoptosis; reduced cell proliferation, migration and invasion; reduced CDK1, Bcl-xL, MMP2/9, CCND1, SMARCD1 mRNA or protein expression; and induced P53 expression. Dual-luciferase reporter assay indicated miR-490-3P directly targeted CDK1. In vivo studies showed that miR-490-3P transfection suppressed tumor development and CDK1, Bcl-xL, MMP2/9 expression while inducing P53 expression. These findings indicate that miR-490-3P may target CDK1 and inhibit ovarian epithelial carcinoma tumorigenesis and progression.

Abstract
Background An increasing amount of evidence has revealed that microRNAs regulate various biological processes, including cell differentiation, cell proliferation, apoptosis, drug resistance, and fat metabolism. Studies have shown that miR-93’s targetome in cancer has not been fully defined. Moreover, the role of miR-93 in epithelial ovarian carcinoma (EOC) remains largely unknown. Methods MIR-93 mRNA expression in normal ovarian tissue, benign tumors, borderline tumors, primary ovarian carcinomas, and metastatic omentum was quantified. The ovarian carcinoma cell lines OVCAR3, SKOV3/DDP, and HO8910-PM were transfected with miR-93-5P, after which cell phenotype and expression of relevant molecules were assayed. Dual-luciferase reporter assay and a xenograft mouse model were used to examine miR-93 and its target gene RHOC (Ras homolog gene family member C). Results MIR-93 mRNA expression was significantly lower in ovarian carcinomas and borderline tumors than in normal ovarian tissues (p < 0.05), and was lower in metastatic omentum than in relative primary ovarian carcinomas (p < 0.05). MIR-93 mRNA expression was also negatively associated with differentiation (well vs. poor and moderate) and International Federation of Gynecology and Obstetrics staging (FIGO stage I/II vs. stage III/IV) in ovarian carcinoma (p < 0.05), besides, miR-93 was higher expressed in mucinous adenocarcinoma than the other types (p < 0.05). MiR-93-5P overexpression reduced proliferation (p < 0.05); promoted G1 or S arrest and apoptosis (p < 0.05); suppressed migration and invasion (p < 0.05); and reduced RhoC, P70S6 kinase, Bcl-xL, matrix metalloproteinase 9 (MMP9) mRNA or protein expression; conversely, it induced P53 and cleaved PARP expression (p < 0.05). Dual-luciferase reporter assay indicated that miR-93 directly targeted RhoC by binding its 3′ untranslated region. MiR-93-5P transfection also suppressed tumor development and RhoC expression (determined by immunohistochemistry) in vivo in the xenograft mouse model (p < 0.05). Conclusions This is the first demonstration that miR-93-5P may inhibit EOC tumorigenesis and progression by targeting RhoC. These findings indicate that miR-93-5P is a potential suppressor of ovarian cellular proliferation. The involvement of miR-93-5P–mediated RhoC downregulation in inhibiting EOC aggressiveness may provide extended insight into the molecular mechanisms underlying cancer aggressiveness.

Abstract
Two-micrometer laser vaporization resection has been used in clinic for years, but some patients received the treatment are still faced with excessive and abnormal wound repair which leads to the recurrent of urethral stricture eventually. Fibroblasts play a key role in the processes of "narrow-expansion/operation-restenosis" recurring problems. Here, we investigated the effect of laser fluence biomodulation on urethral scar fibroblasts as well as the underlying mechanism. Urethral scar fibroblasts were isolated and cultured, and laser irradiation (2 μm) was applied at different laser fluence or doses (0, 0.125, 0.5, 2, 8, 32 J/cm(2)) with a single exposure in 1 day. The effect of 2-μm laser irradiation on cell proliferation, viability, and expression of scar formation related genes were investigated. Two-micrometer laser irradiation with intermediate dose (8 J/cm(2)) promoted scar fibroblasts proliferation and reactive oxygen species (ROS) production, while higher doses of 32 J/cm(2) are suppressive as it decreased the survival rate, viability, and proliferation of fibroblasts. In addition, qRT-PCR and Western blotting results both proven that collagen type I, collagen IV, MMP9, and CTGF display significant increase, yet the TGF-β1 expression was severely reduced at intermediate dose (8 J/cm(2)) group when compared with the others groups. Our findings suggest the scar formation-related genes are sensitive to intermediate laser irradiation dose, the most in scar fibroblasts. We revealed the bioeffect and molecular mechanism of 2-μm laser irradiation on rabbit urethral scar fibroblasts. Our study provides new insights into the mechanisms which involved in the excessive and abnormal wound repair of 2-μm laser vaporization resection. These results could potentially contribute to further study on biological effects and application of 2-μm laser irradiation in urethral stricture therapy.

PLoS One 2014; 9:e88184. [PMID: 25136829 PMCID: PMC4138026 DOI: 10.1371/journal.pone.0088184] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2013] [Accepted: 06/30/2014] [Indexed: 11/24/2022] Open
Abstract
Aim Tissue inhibitor of metalloproteinase (TIMP2) is involved in the regulation of matrix metalloproteinase 2 (MMP2) and shown to implicate in cancer development and progression. The results from the published studies based on the association between TIMP2 -418 G>C polymorphism and cancer risk are inconsistent. In this meta-analysis, we aimed to evaluate the potential association between TIMP2 -418 G>C polymorphism and cancer risk. Methodology We searched PubMed (Medline) and EMBASE web databases to cover all studies based on relationship of TIMP2 -418 G>C polymorphism and risk of cancer until October 2013. The meta-analysis was performed for selected case-control studies and pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated for all genetic models. Results A total of 2225 cancer cases and 2532 controls were included from ten eligible case-control studies. Results from overall pooled analysis suggested no evidence of significant risk between TIMP2 -418 G>C polymorphism and cancer risk in any of the genetic models, such as, allele (C vs. G: OR = 1.293, 95% CI = 0.882 to 1.894, p = 0.188), homozygous (CC vs. GG: OR = 0.940, 95% CI = 0.434 to 2.039, p = 0.876), heterozygous (GC vs. GG: OR = 1.397, 95% CI = 0.888 to 2.198, p = 0.148), dominant (CC+GC vs. GG: OR = 1.387, 95% CI = 0.880 to 2.187, p = 0.159) and recessive (CC vs. GG+GC: OR = 0.901, 95% CI = 0.442 to 1.838, p = 0.774) models. No evidence of publication bias was detected during the analysis. Conclusions The present meta-analysis suggests that the TIMP2 -418 G>C polymorphism may not be involved in predisposing risk factor for cancer in overall population. However, future larger studies with group of populations are needed to analyze the possible correlation.

Abstract
Epithelial to mesenchymal transition (EMT), invasion, and motility are essential steps in colorectal cancer (CRC) metastasis regulated by HIF-1α and NF-κB. Since HSP90 activates HIF-1α and NF-κB, we hypothesized that inhibition of HSP90 leads to inhibition of HIF-1α and NF-κB resulting in inhibition of EMT, invasion, and motility. Treatment of colorectal cancer cell lines HT-29 and HCT-116 with ganetespib at 50 nM for 24 h inhibited EMT (downregulated vimentin and upregulated E-cadherin), matrigel invasion, and spheroid migration. Ganetespib treatment or HSP90 knockdown downregulated molecular pathways associated with EMT, invasion, and motility. The overexpression of HIF-1α or NF-κB resulted in increased EMT, invasion, and motility in both cell lines and these effects were inhibited by ganetespib. Similar effects were observed in animal xenografts treated with ganetespib. Taken together, our data demonstrate for the first time that inhibition of HSP90 downregulates both HIF-1α and NF-κB leading to inhibition of EMT, motility, and invasiveness in colorectal cancer.

Abstract
BACKGROUND The natriuretic peptide receptor-A (NPRA) has been investigated as a receptor of natriuretic peptides in the cardiovascular system. In this study, however, we analyze the expression status of NPRA and the relationship with tumor invasion in esophageal squamous cell carcinoma (ESCC) for the first time. METHODS Western blots were used to examine the expression status of protein in human ESCC cell lines. Then, we used immunohistochemistry to detect the expression of NPRA in 45 ESCC specimens and 40 corresponding nontumor tissues. The clinical data were analyzed through statistical methods. Sh-RNA-NPRA was transfected into Eca109 cells to detect the relationship between NPRA and cell invasion through transwell assays. RESULTS In esophageal squamous cells, the expression of NPRA was strongly detected in the cytoplasm, while undetectable or very weak in the nucleus. The positive rates of NPRA in cancer tissues are significantly higher than that in nontumor tissues (P<0.05). Clinicopathological analyses revealed that increased NPRA expression correlated with differentiation and TNM stage (P<0.05), while it showed no statistically significant association with age, gender, and lymph node metastasis. In analysis of prognosis, we found that highly.Transwell assays showed that NPRA promoted Eca109 cell migration and invasion in vitro and may be involved in MMP2 and MMP9 activation. CONCLUSIONS NPRA protein is highly expressed in ESCC tissues and could promote Eca109 cell migration and invasion in vitro.

Abstract
In the United States, colorectal cancer (CRC) is the third leading cause of cancer mortality, with limited treatment options for those with advanced disease. Matrix metalloproteinases (MMPs) are important for maintaining extracellular homeostasis but also play a prominent role in cancer cell invasion and dissemination. Expression levels of MMP-1, -2, -7, -9 and -13 correlate with worse outcomes; MMP-12 expression appears to be protective. Hence, MMPs are attractive therapeutic targets. Previous clinical trials using broad-spectrum MMP inhibitors were disappointing because of off-target toxicity and lack of efficacy. Now, the availability of safer, more selective inhibitors has renewed interest in therapeutic targeting of MMPs.

Abstract
PURPOSE To verify the expression of matrix metalloproteinase (MMP)-9 in stent-induced hyperplastic tissue from patients with colorectal cancer who received colorectal stents as a bridge to surgery. MATERIALS AND METHODS This prospective study was institutional review board-approved, and informed consent was obtained from all patients. Eleven patients (nine men, two women; mean age, 67 years; age range, 53-82 years) with malignant colorectal obstructions who received a colorectal stent between May and December 2010 were included. Tissue specimens were analyzed for MMP-9 and MMP-2 expression. After resection, the tissue was segmented into three parts: tumor tissue, stent-induced tissue hyperplasia, and normal colon tissue. MMP-9 and MMP-2 expression were determined by using zymography, Western blot analysis, and real-time reverse-transcription (qRT) polymerase chain reaction (PCR). Significance of differences between groups was evaluated with Friedman analysis of variance test. Signed-rank test was used to determine differences between malignant tumor tissue and stent-induced hyperplastic tissue groups. RESULTS Stent placement was technically successful in all 11 patients. Stent-induced hyperplastic tissues were found in all patients. Zymography (P = .003) and Western blot analysis (P = .008) showed that expression of MMP-9 was higher in malignant tumor tissue and stent-induced hyperplastic tissue groups compared with normal colorectal tissue group, demonstrating significant differences between groups but no significant differences between malignant tumor and stent-induced hyperplastic tissues. As for results of qRT PCR analysis, the stent-induced hyperplastic tissue group showed increases in messenger RNA expression level of MMP-9 compared with the malignant tumor tissue group (50.42-fold ± 66.30 higher). CONCLUSION High expression of MMP-9 is closely associated with stent-induced colorectal tissue hyperplasia in patients with colorectal cancer.
